Using your DC Sports air filter is easy. First, remove your old air filter from the intake tubing. Then, take your new DC Sports air filter and bolt the urethane base flange directly to the intake tubing without needing additional couplers. Don't forget to use the included clamp to secure it. As for maintenance, check the filter regularly. If it looks dirty or clogged, clean it with a proper air filter cleaner. Make sure to let it dry completely before reinstalling. When handling the filter, be gentle to avoid damaging the cotton gauze element. And store it in a dry place when not in use.
